managing two sites with drupal

I'm not very familiar with drupal. Honestly, I use it because long time
ago my brother recommend it, but I have no much idea about it.
So, when I was thinking on maintaining two blogs (the old and the new
one) I first though on adding a new taxonomy vocabulary and the assign
it to all old entries. In other words, tag all the old content with
"old_content" tag.

But, after some quick reply in commandob mailing list, I start looking
at drupal multi-site management, and I have to say that it's really
simple.

I wanted to manage two sites: blog.emergetux.net and
oldblog.emergetux.net. So, after creating both DNS entries and
modifying ISPconfig co-domain configuration, I only had to create a
couple of directories under sites (one for each site I wanted to
manage) and add a custom setting.php file:

sites/default/settings.php
sites/emergetux.net/settings.php
sites/oldblog.emergetux.net/settings.php

[note] emergetux.net includes *.emergetux.net except oldblog with is
explicity defined.

If you want to manage many different sites you have 2 options:

1) use different databases for each site. This is not my case.

2) use one database but use different table name for each site. You can
do it by adding a table prefix to each site.

So, in my case, I left old blog without prefix and added 'new_' prefix
to new one.

sites/emergetux.net/settings.php
$db_url = 'mysql://username:password@localhost/databasename';
$db_prefix = 'new_';<br>
sites/oldblog.emergetux.net/settings.php
$db_url = 'mysql://username:password@localhost/databasename';
$db_prefix = '';

[note] default site uses same conf as emergetux.net site.

And that's all!
